Mozza - did you ever feel the need to caress your EX1, kiss her, compliment her, cuddle with her afterward?
Honestly, it was 16 years ago and I don't remember (but I remember the fantastic sex!).
My explanation for why he was so cuddly this time is that he doesn't like to be "a dick". Last time, he tried to fulfill susana4's physical needs and this time, the emotional needs. He wants her to love him, forgive him for what he's doing. He can't bear the idea that someone somewhere doesn't like him. For him too, it can be hard to let go of the intimacy (not sex). My WAW and I ML three times during the week of S talks. She's the one who came to the bedroom to cuddle, likely because she felt the upcoming loss. She was visibly distressed and was seeking comfort, which I provided.
I'm no vet so I don't want to weigh on the DB techniques, but rather share my experience. I don't know what's going on in H's head and, as I wrote above, I think susana4 should continue along this path, for what it's worth.
